GEARING.

Specification of Letters Patent.

Application filed April 80, 1908. Serial No. 430,098.

Be it known that I, ALEXANDER T. Brown,

I of-Syracuse, in the county 'of Onondaga and State of New York, have invented a certain new and useful Gearing, of which the following is'a specification. My invention has for its object the production of a caring particularly applicable for use in se f-propelled vehicles, which is highly simple and compact in construction, especially durable'and efiective in use, and facilitates ready access to, and removal of, parts thereof; and to this end, the invention consists in the combinations and construetions hereinafter described" and pointed out in the claims. I

In describing this invention, reference is had to the accompanying drawing, in which like characters designate correspondingparts in all the views.

I Figure 1 is a sectional view, partly in elevation, of the-gearing embodying one form of my invention. Fig. 2 is a sectional view taken on line A-A, Fig. 1. Fig. 3' is a detail sectional view illustrating the intermediate or reverse gears, and parts of the shifting means. Fig. 4 is a face view of one section of the casin Fig. 5 is a plan view, partly in section, 0 a portion of another section of the casing, the rods for supporting the shifting means being also shown. Fig. 6 is an inner face view of a part of the section of the casing illustrated in Fig. 4. Fig. 7 is a detail sectional view taken, on line B-B,

51y gearing includes, generally, driving and driven members 1 and 2, power-transmitting means for connecting said members,

and a suitable support. This support is here shown as a casing inclosmg the dri and driven members andthe power-transmitting means, but it is obvious that said members and power-transmitting means may be carsame;

ried by a support notserving to incase the The driving and driven members 1 and 2 are here shown as shafts arranged with their axes at an angle toeach other, the driving member 1 bein by the member 3 and coacting with the gears 5. It will, however, be understood by those skilled in the art that the driven member 2 may be continuous from end to end, or may be unprovided with an equalizing device, or may be provided with any other suitable Patented July 21, 1914.

construction of e ualiz'ing device, and that the driven and driving members may be arranged otherwise than with their axes at an angle to each other. It will also be understood that the driving member is not necessarily the power-shaft of a self-propelled vehicle, and that the driven member instead of constituting the rear axle of a self-pro pelled vehicle may consist of any other shaft.

or revoluble part suitably connected to such a rear axle or to the driving wheels of a. selfpropelled vehicle, or to any other moving part or mechanism.

Motion is communicated to the driven member 2 by a suitable power-transmitting wheel, as a bevel gear 7 concentric with the driven member and illustrated as fixed to the revoluble member 3. of the equalizing device. In case the driven member 2 is unprovide'd with an equalizing device, the bevel gear 7 is mounted directly upon such driven member in the same manner as one of the gears 5 or in any other suitable manner.

The casing 4 preferably consists of separable sections, and as here shown said casing is divided in a direction substantially.

lengthwise of the axis of the driven member 2, opposing surfaces of the sections of the casing being provided .with marginal flanges and being arranged between the axis of the driven member 2 and the periphery of the gear 7. Said casing 4 is referably provided with a partition 8, compartments at opposite sides of the partition, and a passageway 9, the partition 8 being fixed relatively to, and usually formed integral with, the front section of the casing and having opposite sides thereof united to opposing walls of the front section of the casing, as the top and bottom walls thereof, and the passageway 9 being interposed between an edge 10 of the partition 8 and the contiguous inner surface of the external wall of the casing, and connecting the interiors of compartments of the front and rear sections of the casing. Said passageway permits the gear 7 and the equalizing device to extend therethrough from the interior of the rear section of the easing into the interior of the front section thereof. The rear section of the casing 4 is secured to the front section of the casing by any desirable means, as screws 11, passed through the marginal flanges of; said sections, and is provided with suitable means for supporting the driven member and the equalizing device, and with an opening 12 in the front face of the section normally closed by the front section of the casing, and formed of greater size than the bevel gear 7 and the equalizing device. Preferably the rear section of the casing is composed of relatively strong metal, as a forging or a malleable iron or steel casting, and the front section thereof is constructed of relatively light metal, as aluminum, in order that the casing may be of maximum strength and of minimum weight. A casing constructed as described is compact, strong and durable and particularly suitable for use with the remaining parts of my gearing, but it will be understood, by those skilled in the art, that the parts of my gearing may be inclosed in any other suitable sectional casing instead of the one shown and described herein.

In the preferable construction of the cas-. ing 4 tubular shells 13 are removably secured by bolts 14, or other suitable means, to flattened faces 15 at opposite sides of said casing. These shells 13 serve to inclose the portions of the driven member projecting beyond the casing 4, but if desired said shells 13 may be dispensed with.

As clearly shown in Fig. 1, the driving member 1 is jjournaled in bearings 16 and 17 detachably mounted, respectively, in the partition'S and the opposing wall 18 of the front section of the casing, and the driven member 2 is supported within the rear sec- 5 tion of the casing by the gears 5 which engage the circular series of pinions 6. These gears 5 are preferably formed with central openings 19. of angular cross-section, and the contiguous ends of the sections of the driven member 2 are of similar shape so that said sections of the driven member may be moved endwise into and out of operative engagement with the gears 5. The driving and driven members 1 and 2 of my gearing may, however, be otherwise supported by the easing 4.

The illustrated means for supporting the bevel gear 7 and the equalizing device consists of hubs 20 and 21 projecting from opposite sides of the revoluble member 3 of the equalizing device, and antifriction bearings 22 and 23, one bearing being mounted within the hub 20 and the other encircling the hub 21. The bearing 22 encircles one end of a sleeve 24 and is interposed between annular shoulders 25 and 26 spaced apart laterally from each other and provided, re spectively, upon the inner face of the hub 20 and the periphery of the contiguous end of the sleeve 24. This sleeve 24 which forms a support for the bearing 22 is, passed through and fits circular openings in supporting parts 27 and 28 arranged at the left hand side of the gear 7 and fixed to the and having their inner faces arranged concentric with the driven member2 and spaced apart therefrom. The supporting part 27 5 is split and provided with a clamping screw interior of the rear section of the casing 29, Fig. 4, and the inner face of the other I supporting part28 and the contiguous end of the sleeve 24 are threaded and engaged with each other, and said sleeve is provided with means, as sockets 30 for facilitating I turning thereof. E As best seen in Fig. 1, the bearing 23 is iheld in a su porting part or internal hub 31 fixed to t e interior of the rear sectlon i of the casing at the right hand side of the j gear 7 and provided with a detachable segment 32, Fig. 6, secured in position by suitable means, as screws 33. One side of the bearing 23 is engaged with an annular shoulder 34 at the base of the hub 21, and

bearing 35. As the sleeve 24 is adjusted lengthwise of the driven member 2 toward the right, the bevel gear 7 and the antifriction bearings 22 and 23 are moved axially j toward the thrust-bearing 35 for adjusting the mesh of the gear 7 with its driving pinion, and when the segment 32 is detached, and the clamping screw 29 is loosened, and the sleeve 24 is moved toward the left out of engagement with the bearing 22, the gear 7 j and the equalizing device are free from the supporting parts therefor within the casing.

In the preferable construction of my invention the power-transmitting means for connecting the driving and driven members i 1 and 2 includes a transmission wheel, as a l bevel gear 36, meshing with the bevel gear 7, f and means connecting the driving member j 1 and the gear 36 for rotating said gear at 5 different speeds and in opposite directions. $11; is obvious, however, that a driven mem 5 her or an equalizing device supported as de-. scribed may be actuated by a driving gear *not rotating at difl'erent speeds or opposite directions. The gear 36 is loosely mounted-on the driving member 1 between the partition 8 and the wall 18 of the front g the opposite side of the internal section of 1 said bearing is engaged by a suitable thrustsection of the casing, and is provided with a sleeve 37 extending toward the wall 18 and usually formed of'angular crosssection.

The means for rotating the gear 36 at difi'erent speeds and in opposite directions comprises ears 38 and 39 of unequal diameter revolu le with the gear 36, means for locking the driving member 1 to the gear 36, a gear 40 revoluble with the driving member and arranged between the partition 8 and the gear 36, a countershaft 41 having its ends jo-urnaled in bearings detachably mounted in the partition 8 and the opposing wall 18 of the front section of the casing, a gear 42 fixed to the countershaft 41 and meshing with the gear 40, gears 43 and 44 of unequal diameter revoluble with said countershaft and adapted to mesh respectively with the gears 38 and 39, an intermediate gear or gears for effecting the reverse or backward movement of the gear 36, and means for moving a number of said gears endwise. Of the gears revoluble with the gear 36, the one 39 oflesser diameter is arranged between the gear 38 and the casing wall 18 and is shiftable endwise along the sleeve 37, and of the gears revoluble with the countershaft and coacting with the gears 38.

and 39, the one 43 of lesser diameter is ar ranged about midway of the countershaft and is shiftable along said countershaft. It is obvious, however, that the gears 38 and 44 mayi be capable of endwise movement if desire The means for locking the driving member 1 to the gear 36 is here shown as coacting clutch-members 45 and 46 fixed respectively to the driving member 1 and the gear 39, but it is apparent that the clutch-member 46 may be carried directly by the sleeve 37 instead of by the gear 39.

In the preferable construction of my gearing, I employ two intermediate gears 47 and 48 for effecting the rotationof the gear 36 in the reverse orbackward direction. These gears are of unequal diameter, are revoluble together, are adapted to mesh, respectively, with the gears 38 and 43, and are movable endwise into and out of operative engagement with the gears 38 and 43. Said gears 47 and 48 aremountedon a shaft 49 which is supported at its ends by op osing bearings 50 and 51 carried by the ont section of the casing near the base thereof, is movable endwise with the gears 47 and 48, and is provided with a relatively fixed arm 52 extending toward the top of the casing and having its free end provided with suitable engaging means, as jaws spaced apart from each other. The gears 47 and 48 are preferably so arranged relatively to the gears 38 and 43 that the gear 48 meshes with the gear 43 just before the gear 47 meshes with the gear 38. To those skilled in the art, it is apparent that a single intermediate gear may be used instead of two of such gears, and that in such event, it would be necessary to give the single gear twice the movement of the gears 47 and 48.

The means for moving endwise the shiftable gears 39 and 43 and 47 and 48, just described, consists of sliding members 53 and 54, the arm '52 previously described, and a shifting member 55. Said sliding members 53 and 54 aremounted on a pair of fixed rods 56 and 57 spaced-apart and supported at the top of the casing 4 by the partition 8 and the opposing wall 18 of the casing. These sliding members 53 and 54 are provided with depending forks respectively engaged with the gears 39 and 43, and opposing surfaces of said members are provided with engaging means, as aws 58 and 59, the jaws 58 on the member 53 being spaced apart from each other and arranged at one side of the upper end of the arm 52, and the jaws 59 on the other member spaced apart from each other and the jaws 58 and arranged at the other side of the upper end of the arm 52.

The shifting member 55 is preferably fixed to an-actuating rod 60 arranged between the rods 56 and 57 and is movable about its axis and lengthwise thereof. Said member 55 is provided with a depending arm which is arranged in position to meet with the engaging means or jaws of the upper end of the arm 52, or with the engaging means or jaws 58 and 59 of the sliding members 53 and 54, and is movable about the axis of the rod 60 from engagement with the jaws of oneof said parts into engagement with the jaws of the predetermined part, and is then movable lengthwise of such axis for shifting said predetermined art. I do not here illustrate any means or moving the rod 60,

54 being i since any suitable device may beused for this purpose. I

In the manufacture of my gearing, the driving member 1, the countershaft' 41, the shaft 49 and the rods 56, 57 and 60 arefitted to the front section of the casing, the driven member and the equalizing devlce are fitted to the rear section of thecasing, the-sections of the casing are shifted relatively to each other to bring theaxes of the drivin and driven members into the proper re ation relatively to each other, and then the holes for the securing screws 11 are drilled in said sections. The construction of the casing of my gearing-thus renders it possible to reduce to a minimum the labor and expense of fitting to said casin the parts carried thereby. Moreover, sai casing-provides a bearin for the'driving member at a minimum istance fromthe axis of the'driven member, and this renders the gearin more compact, and durable than would ie the case were said bearingspaced apart a greater i distance from the driven member.

gear 7 may be withdrawn as a whole through the opening 12 in the front face of said rear section. It is thus apparent that any. part of my gearing may be removed with minimum effort. I
